Resolution Note:
Prior to 2022.2, unlike Mono, IL2CPP cached the attribute instances returned by GetCustomAttributes. This was only noticeable if a custom attribute class was mutable, which is the case here. This change relied on a larger refactor of custom attribute support and we don't plan on back porting it.
